Wombat: In an interview with NBC's Matt Lauer in 2007, William revealed that "wombat" was Princess Diana's nickname for him when he was a kid. "It kind of stuck with me. I can't get rid of it now," William said. "It began when I was 2. I've been rightfully told because I can't remember back that far. But we went to Australia with our parents, and the wombat, you know, that's the local animal . . . So I just basically got called that. Not because I look like a wombat — or maybe I do."
